New Accounting Ref Date

Renalytix plc (LSE: RENX) (OTCQB: RNLXY), a precision medicine diagnostics company focussed on kidney disease, announces that it has resolved to change the Company's accounting reference date.

The Company's financial year‑end will change from 30 June to 31 December.

Accordingly:

 Following the Company's audited results for the year ended 30 June 2025, the current accounting period has been extended and will now end on 31 December 2026, resulting in an 18‑month accounting period.

 The Company published interim results for the six‑month period ended 31 December 2025 in March 2026.

 The Company will publish unaudited interim results for the 12‑month period ending 30 June 2026 in late October 2026.

 The Company will publish audited accounts for the 18‑month period ending 31 December 2026 no later than 30 June 2027, in accordance with AIM Rule 19.

 Thereafter, the Company will report on a 12‑month financial year ending 31 December, with interim results covering the six months to 30 June each year.

The Board believes that the change in accounting reference date will better align the Company's financial reporting with its operational and strategic planning cycle. Following the recently announced multi-year partnership with Quest Diagnostics (“Quest”), kidneyintelX.dkd is expected to be available for physician ordering through Quest's system in the first quarter of 2027. As a result, the Company is increasingly using the calendar year as the basis for forecasting, budgeting, and evaluating commercial performance.

The change to a 31 December year-end will therefore better align the Company's external financial reporting with its internal budgeting and forecasting processes and the expected timing of the next phase of its commercial growth.
